Recently upgraded my iPhone 6 Plus to iOS 10. Soon after upgrading I started to notice a intermittent issue where the phone would randomly jump to a black screen with a white loading spinner in the middle (similar to what you see when shutting the phone down) and then after about 5 seconds it will take me back to the lock screen. I'm still able to unlock the phone using the fingerprint reader (so the phone hasn't actually rebooted) and the phone appears to function as per normal.
It is extremely annoying as it can happen in the middle of any phone function (including taking and making calls) and on some days can happen more than half a dozen times.
So far I have noticed it happening when using the following Apps:
- Google Chrome
- Microsoft Outlook App
- Facebook App
- Apple Music App (completely stopped a playing track at the time)
Not sure if it's just random or being triggered by particular apps. When it happens whilst Google Chrome is open the next time I open Chrome it reports that Chrome crashed and "would I like to restore my pages?".
I haven't done a fresh iOS 10 install but I'm reluctant to do this as it takes time and risks my data and setup on the phone now (even though I do have a iCloud backup).
I have also since upgraded to iOS 10.0.2 (14A456) but the problem still remains.
Is there a way to view diagnostic, error or event logs on the OS to see what might be happening immediately before the black screen occurs?
Anyone else experiencing the issue?
